What is PCR? Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA. This DNA region can be anything the …

PCR (Polymerase Chain Reaction) is a vital technique in molecular biology, enabling researchers to amplify specific DNA fragments exponentially. Essential for cloning, forensics, and medical …

DNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add.

DNA polymerase is the enzyme responsible for synthesizing new DNA. To do this, DNA polymerase moves along a template strand and adds complementary nucleotides one at a time to a growing DNA …

On the leading strand, DNA polymerase catalyzes the continuous synthesis of DNA in the 5' to 3' direction. However, on the lagging strand, DNA synthesis occurs in short fragments called Okazaki …

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an …

DNA replication is a complex, fast, and precise process involving enzymes like topoisomerase, helicase, and polymerase. In E. coli, polymerase can replicate up to 700+ base pairs per second.

One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, …

Transcription involves rewriting genetic information from DNA to mRNA, with RNA polymerase playing a crucial role. In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre …
